Fig. 6


Spatial distribution of the RR Lyrae stars found in this survey. RR Lyrae stars in the range of distances of ω Centauri are indicated with either black or red dots. For the later we have measured radial velocities. Other RR Lyrae stars in the field (in either the foreground or background) are plotted with small star symbols. The black dashed circle corresponds to the tidal radius of rt = 57 arcmin of ω Centauri. The solid square and dashed rectangle show the regions explored by Leon et al. (2000) and Da Costa & Coleman (2008).

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
